FIELD OF THE INVENTION
[0001] The present invention relates to a method and a device for treatment of human excrement
by collecting and dehydrating the excrement as expelled from human body and more particularly
to a method and a device for treatment of human excrement through collection and dehydration
of primary excrement as expelled from human body without polluting the environment.
BACKGROUND OF THE INVENTION
[0002] In many areas where waterborne system is not available, people usually collect excrement
in a container as it is expelled from the human body. The excrement is usually piled
up with straw for undergoing anaerobic degradation. Such a heap sends forth a foul
smell which pollutes the environment.
US3921228A describes a decomposition toilet that includes a heating means. This document is
considered as the closest prior art.
[0003] There are also a number of previously known biological toilets to improve the above
situation. However, these biological toilets are not satisfying in terms of dehydration
efficiency and maintenance point of view because excrement stains the passageway causing
unpleasant feeling to next user and excrement forms a high pile getting difficult
to be dehydrated particularly in the center portion and new excrement hinders dehydration
process. The present invention is a need for an improved method and a device to overcome
the shortcomings of the prior art.
OBJECTS OF THE INVENTION
[0004] It is an aim of present invention to provide a method for treatment of human excrement
by collecting and dehydrating the excrement expelled from human body.
[0005] Another aim of present invention is to provide a device for treatment of human excrement
by collecting and dehydrating the excrement expelled from human body.
SUMMARY OF THE INVENTION
[0006] To achieve the aforementioned aims, one aspect of the present invention provides
a method for treatment of human excrement, according to the features of independent
claim 1. Said method comprises, among others, the step of providing a chamber having
a top opening through which excrement enters the chamber;
The method also comprises the step of allowing the excrement to form a layer inside
the chamber by setting up a storing porous plate crossing the whole length and whole
width of an upper half of the interior of the chamber, wherein the upper part of said
plate features to have a protrusion in the form of an equilateral-triangular base
pyramid topped vertically under the centre of the outlet of the top opening and the
lower side of equilateral-triangular base intersected perpendicularly to the central
line of plate, and the plate further slopes downwardly and then horizontally away
from top opening in the form of a series of corrugations whereby the excrement moves
down the pyramid and the slope and then across the plate by gravity;
The method further comprises the step of allowing liquid urine to fall down into the
urine storing region of the chamber through perforations in the porous plate;
The method also further comprises the step of setting up two solid excrement storing
regions namely a front storing region located under the top opening and a rear storing
region located away from the top opening, and the regions are separated by mounting
a vertical baffle on top of said corrugated plate, whereby solid excrement is stored
firstly at the front storing region and secondly at the rear storing region;
The method still further comprises the step of dehydrating the solid excrement by
ventilating the chamber interior by means of a ventilation system located at the top
ceiling region of the front storing region which draws air in through the end wall
of the rear storing region, down through the porous plate into the urine storing region
and backup through the porous plate before exiting out through the ventilation system;
The method can also comprise the step of providing an indirect heat source inside
chamber wherein heat penetrates the solid excrement layers without touching.
[0007] Another aspect of the present invention provides a device for treatment of human
excrement according to independent claim 3. This device comprises a chamber having
a top opening through which excrement enters chamber;
According to one embodiment of the present invention, said top opening is defined
by a bowl having an upwardly-tapered interior wherein the top entrance inner circumference
is smaller than the interior circumference and said bowl is provided therein with
an inclined inner trough and a vertical inner trough opposed to the inclined inner
trough both are extending downwardly, thereby forming a tunnel having an outlet and
providing a vertical passageway penetrating into the chamber interior to minimize
visibility. Each of the inner surfaces of the troughs is covered with a coating that
improves the sliding of excrement. The inclined trough has a bottom end centered vertically
to a central point of the top entrance of the bowl;
According to another embodiment of the present invention, said top opening is defined
by a squat pan having an oblong interior, and the squat pan is provided therein with
an inclined inner trough and a vertical inner trough opposed to the inclined inner
trough both are extending downwardly, thereby forming a tunnel having an outlet and
providing a vertical passageway penetrating into the chamber interior to minimize
visibility. Each of the inner surfaces of the troughs is covered with a coating that
improves the sliding of the excrement. The inclined trough also has a bottom end centered
vertically to a central point of the top entrance of the squat pan;
The device comprises a storing porous plate mounted crossing the whole width and whole
length of an upper half of the interior of the chamber wherein the upper part of the
plate features to have a protrusion in the form of an equilateral-triangular base
pyramid topped vertically under the centre of the outlet of the top opening and the
lower side of equilateral-triangular base intersected perpendicularly to the central
line of the plate, and the plate further slopes downwardly and then extends horizontally
away from the top opening in the form of a series of corrugations whereby the excrement
moves down the pyramid and the slope and then across the porous plate by gravity,
whereas the liquid urine falls down into the urine storing region of the chamber through
perforations in the porous plate;
The device further comprises two solid excrement storing regions namely a front storing
region located under the top opening and a rear storing region located away from said
top opening, each region being separable by a vertical baffle on top of said corrugated
plate, whereby the solid excrement is stored firstly at the front storing region and
secondly at the rear storing region;
The device still further comprises a means of dehydrating the solid excrement layers
by ventilating the chamber interior by means of a ventilation system located at the
top ceiling region of front storing region which draws air in through the end wall
of rear storing region, down through the porous plate into the urine storing region
and backup through the porous plate before exiting out through the ventilation system;
The device can also comprise a means of providing an indirect heat source inside the
chamber wherein heat penetrates solid excrement without touching;
The invention will now be described in detail, by way of example, with reference to

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0009] Fig.1 shows a perspective view of a bowl (1) to be used in the present invention.
The bowl (1), provided for sitting on to defecate and urinate, includes an upwardly-tapered
interior in a way that the top entrance inner circumference is smaller than the interior
circumference of the said bowl (1) to avoid the excrement staining on the inner wall
thereof. The bowl (1) further includes an inclined inner trough (2) extending inwardly
and downwardly and a vertical inner trough (3) opposed to the inclined trough (2),
with each of the troughs (2) and (3) having a curved surface forming a vertical passageway
having an outlet (4) penetrating into the interior of the chamber (5) to minimize
visibility. Each of the inner surfaces of the troughs (2), (3) is covered with a coating
that improves the sliding of excrement. The inclined trough (2) has a bottom end centered
vertically to the central point of the top entrance of the bowl (1) so that when human
body sit on the bowl (1) at normal posture, the anus of the human body is at a vertical
position above the central area of the outlet (4), as clearly shown in Fig.1, enabling
solid excrement enters the chamber (5) directly through the passageway, whereas urine
pushes the remaining solid excrement still left behind on the inclined trough (2)
into the chamber (5).
[0010] Alternatively, a squat pan (1a) of Fig.2 is used instead of the bowl (1) of Fig.1.
As shown in Fig. 2, the squat pan (1a), provided for squatting across to defecate
and urinate, includes an oblong interior. The squat pan (1a) further includes an inclined
inner trough (2a) extending inwardly and downwardly and a vertical inner trough (3a)
opposed to the inclined trough (2a) forming a vertical passageway having an outlet
(4a) penetrating into the interior of the chamber (5) to minimize visibility. Each
of the inner surfaces of the troughs (2a), (3a) is covered with a coating that improves
the sliding of the excrement. The inclined trough (2a) here also has a bottom end
centered vertically to the central point of the top entrance of the squat pan (1a)
so that when human body squat across the squat pan (1a) at normal squatting posture,
the anus of the human body is at a vertical position above the central area of the
outlet (4a) enabling solid excrement enters the chamber (5) directly through the passageway,
whereas urine pushes the remaining solid excrement still left behind on the inclined
trough (2a) into the chamber (5) as clearly shown in Fig.2. Regardless of the difference
between the bowl (1) and the squat pan (1a), their respective inner troughs (2,2a)
and (3,3a) form an outlet (4,4a) providing a vertical passageway between them as the
top opening of the chamber (5).
[0011] Fig.3 shows a perspective view of a storing porous plate (6) to be used in the present
invention. The upper part of the plate (6) features to have a protrusion in the form
of an equilateral-triangular base pyramid (6a) wherein the lower side of the equilateral-triangular
base of the pyramid (6a) intersects perpendicularly to the central line of the plate
(6), and the plate (6) further slopes downwardly and then extends horizontally in
the form of a series of corrugations (6b) wherein holes are distributed on the lower
surface of the slope and on the surface of the corrugated area (6b) to allow urine
falling down and to allow air penetration through the plate whereby a vertical baffle
(6c) is fixed on top the corrugated area (6b).
[0012] As shown in Fig.4, the chamber (5) having topped with a bowl (1) as per Fig.1 is
defined by a first end wall located adjacent to the top opening, a second end wall
located away from the top opening, and a pair of side walls (only one is shown) extending
between the end walls. The storing porous plate (6) as shown in Fig. 3 is mounted
across the whole length and whole width of the upper half of the interior of the chamber
(5) wherein the top of the pyramid (6a) is located vertically under the center of
the outlet (4) of the top opening and the lower side of the equilateral-triangular
base intersects perpendicularly to the central line of the plate (6) whereby the pyramid
(6a) provides three slopes to widen the movement of excrement down the main slope
of the plate (6) and then across the horizontal corrugated plate (6b) by gravity.
The vertical baffle (6c) divides the upper chamber interior into two separated storing
regions namely a front storing region (13) and a rear storing region (14), wherein
solid excrement is stored firstly at the front storing region (13) and secondly at
the rear storing region (14). The urine falls into the urine storing region (15) through
holes in the porous plate (6). A set of ventilation system comprising of a ventilating
duct (8) topped with an exhaustion fan (9) and a wind turbine (10) locates at the
top ceiling region of the front storing region (13) drawing air in through the end
wall (11) of rear storing region (14), down through porous plate (6) into urine storing
region (15) and backup through the porous plate (6) before exiting out through the
ventilating system. An indirect heat source (7) locates at the rear storing region
(14) to promote dehydration without touching. Excess liquid urine is drained out of
urine storing region (15) through an overflow exit (12) located under plate (6) to
avoid flooding of solid excrement layers. Eventually completely dried organic harmless
substance is obtained through the manhole cover (16) at the rear storing region (14).
[0013] Although embodiments together with structures and functions of present invention
have been described in detail, many modifications and variations may be made from
the teachings disclosed hereinabove. Therefore, it should be understood by those skilled
in the art that any modification and variation equivalent to the scope of present
invention should be regarded to fall within the scope of the appended claims.
